You don't have x264 encoder installed and there was typo in command:
###
wget -O - http://www.bunkus.org/gpg-pub-moritzbunkus.txt | sudo apt-key
add -

su

echo -e "deb http://www.bunkus.org/debian/wheezy/ ./\ndeb-src
http://www.bunkus.org/debian/wheezy/ ./\n"
>/etc/apt/sources.list.d/mkvtoolnix.list

aptitude update && aptitude install x264 mkvtoolnix mkvtoolnix-gui
###


You must use 2 terminal window as one liner mess up with x264.
The "input.mkv" is your oryginal file that you want to re-encode, then
in one terminal window do this:
###
mkfifo /tmp/mplayer.y4m && mplayer -noconfig all -correct-pts -benchmark
-nosound -ass -vo yuv4mpeg:file=/tmp/mplayer.y4m input.mkv
###


and in second terminal window do this:
###
x264 --profile high --preset slow --tune film --ref 5 --mixed-refs
--bframes 3 --b-pyramid strict --direct auto --filter -1:-1 --trellis 2
--partitions all --8x8dct --vbv-bufsize 50000 --vbv-maxrate 20000 --me
umh --keyint 300 --min-keyint 15 --crf 18 --sar 1:1 --threads 3 --level
4.1 -o output.mp4 /tmp/mplayer.y4m
###


then merge everything into mkv:
###
mkvmerge -o output.mkv output.mp4 input.mkv -D -S
###


And why don't use mencoder?
- It could merge/mux into AVI only (MKV and MP4 is messed up);
- It have no level limiter in x264 options.
